Contrast is contrast, there's no "end" to get it out of. To make blacks darker with the current brightness you have to improve the amount of light the panels can block, to keep the same black level with more brightness, you need to do the same. Whether they made the machine brighter is a separate issue from if (how much) they improved contrast.
That said, a lot of folks would welcome increased brightness to go along with improved contrast, it will allow larger screens, or even better contrast (ability to run with lower IRIS settings), and sure probably improved 3D for the folks who care about that

I think they're saying if you buy a 4K machine (doesn't matter who from) in a few months without HDMI 2.0 (all indications are these JVCs won't have HDMI 2.0), then it will be obsolete when HDMI 2.0 is released, as you will have a 4k machine but will likely be unable to view commercial 4k content on it.
Isn't Sony, Benq, Optoma, Epson, etc bringing out projectors? If you buy those, those will not be obsolete? Even the high end models like Runco, SIM2, etc have 1080p models probably coming out soon. Why is it so crazy to buy a jvc now?
All 1080p machines have a similar "problem" this year, they're not 4k, though they don't as much have the problem of being a cart with no horse like a 4k-without-hdmi-2.0 machine is.

The new generation will take a 4k input and do the same, but minimal scaling/processing if any will be required with a 4k native signal(however I feel JVC may adopt some sharpening), when an 1080p signal or less is in putted scaling will be required.
I expect processing will be required with a 4k input signal to make it "compatible" with e-shift. I doubt you can just overlap two 1080p grids raw from a 4k source and get something that looks right. At the very least you've got to toss some info out since you're only flashing 1080p each time. Though it should be possible to have a better result than upconverted since you've got more information to work with.
